APPARATUS FOR DISCHARGIN G VERTICAL RETORTS.

Specification of Letters Patent.

Patented Apr. 11, 1922.

Application filed July 1, 1920. Serial No. 393,292.

To (M 10 [tom it may 0071 com Be it known that I, JULTEN Pin rnns, asubject of the King of Belgium, and a resident of 12 Rue de LaRochefoucauld, Paris, France, have invented new and useful Improvementsin Apparatus for Discharging Vertical Retorts, of which the following isa specification.

The French Patent 484,492 dated February 16th, 1917, describes a methodof dis charging coke, in which the material after having been separatedfrom the upper mass retained in the retort, is transported horizon tallyby a suitable known apparatus. This mechanism, however, does not conveythe material beyond the vertical facing of the retort, and it isnecessary to add a special apparatus for discharging the coke outsidethe retort.

The present invention relates to an apparatus for discharging thematerial at the base of vertical continuous distillation re torts,allowing the material to be conveyed directly outside the retort to thevehicles on which it is to be loaded.

As compared with known apparatus for discharging the material from thewhole length of the retort, the present invention is characterized bythe fact that the hydraulic seal which prevents leakage at the base ofthe retort, instead of extending to form a large reservoir closing inthe whole of the bottom of the retort, and in which the material wouldtherefore have to remain for a considerable time, consists simply of twosmall reservoirs arranged at the sides of the retort and into which thematerial to be discharged passes only for a few moments while beingconveyed by an endless transporter device. This arrangement affords theimportant advantage that the material can absorb only an extremely smallproportion of water during its very short passage through the hydraulicseal.

The annexed sheet of drawings represents by way of example, one form ofconstruction of the invention:

Figures 1-1 is a section upon the centreline of the retort at the baseof the latter.

Figure 2 is a transverse section on line 22 of Figure 1. v

The retort A is sealed at its lower end by two water-spaces a b ofrelatively small dimensions, into which there dip metal parti tions a bso as to provide a hydraulic seal; the reservoirs a and b are arrangedon the centre-line of the retort and on either side thereof, outside theretort chamber.

The discharge of material is effected by an endless conveyor consistingof two side chains 0 0 connected together by slats 0; this conveyorextends over the whole length of the retort,- as far as the driving andidler drums c 0 The material resulting from the distilla tion, forexample coke, rests on the flooring (Z by means of the slatted chain,and can only come into contact with the water during the very short timenecessary for passing through the water seal reservoir a located at theside where the material is discharged.

The endless conveyor chains 0 c are guided in their travel beneath theretort as well as in their passage along the curves of the water-spacesa and b by sliding and protecting surfaces suitably arranged at c 0.

The endless transporting device 0 0 conveys the material directly to thewagons 0, preferably after first making it pass over a riddle consistingof a fixed sieve e in order to remove the finer particles which fallinto a hopper e from which they are evacuated.

The conveyors of an entire battery of re torts may be operated by meansof a single shaft 0 extending along the retorts on one side and drivingthe several drums c by any suitable transmission.

What I claim is:

1. An apparatus for the removal of material from the base of verticalcontinuous distillation retorts comprising an endless conveyor movingthrough the retort chamber, flooring underlying said conveyor andforming the bottom of said chamber, two water seals located at oppositeends of the retort outside the chamber and through which the endlessconveyor passes.

2. An apparatus for the removal of material from the base of verticalcontinuous distillation retorts comprising an endless conveyor movingthrough the retort chamber, flooring underlying said conveyor, andforming the bottom of said chamber, two water seals comprising two waterbasins located at opposite ends of the retort outside the eha1nher, theendless conveyor passing therethrough, partitions fixed to the sides ofthe retort and dipping into the Water basins, said basins consisting ofdepressions in the flooring; in combination with means guiding theconveyor in the curves of the flooring.

In testimony whereof I have signed my name to this specification.
